I am not sure which kernel line to use.
If you have a mtd device mtd0, and want to feed it to ubi, use ubi.mtd=0
command. See modinfo ubi. For kernel command line it is the same, but
you should use 'ubi.mtd=' instead of 'mtd='.
After the mtd is attached, and if mtd device emulation is enabled, ubi
will create MTD devices corresponding to your volumes.

You may use device names. Majors are dynamic and may change.
